Type: in Kew Herb, and Curtis Herb., and of Thelephora 

 setosa in Brit. Mus. Herb. 



Fructifications broadly reflexed and with a narrow, resu- 

 pinate base, or dimidiate, sessile, imbricated, laterally con- 

 fluent, very thin, drying pliable, with upper surface rough 



with coarse, strigose, matted 

 fibers, very shallowly concen- 

 trically sulcate ; hymenium gran- 



^^^^^^^^^^ ular, snuff-brown; in structure 

 'Y^ 150-400 fx thick, with a narrow 



^^s- 2 setigerous layer consisting of 



Seciiou xfs^'^Tpi 16, f. 3. ^he hymenium, and with the 



hyphal layer composed of longi- 

 tudinally arranged, colored hyphae 2 /x in diameter which 

 curve outward and become interwoven to form the upper sur- 

 face of the pileus — no dense, dark zones present; setae scat- 

 tered, 60-75x6 /i, tapering from the base, emerging up to 30 

 Hy some starting from the subhymenium but mostly from the 

 hymenium; spores hyaline, even, 3x2 /i as seen on basidia. 



Pilei of fructifications 1-2^ cm. long, 1-5 cm. broad, some- 

 times resupinate on areas up to 5x3 cm. 



On dead frondose wood on the ground in forests. Cuba, 

 Jamaica, and Venezuela. October to March. 



H. aspera may be recognized by its thin, pliant pileus, which 

 is rough on the upper surface with strigose matted fibers, by 

 granular hymenium which is as granular as in Thelephora 

 terrestris, and by the short, brighter-colored mycelial strands 

 which form the resupinate margin.
